I recommend the Shiseido eyelash curler.

This is the famous Shiseido eyelash curler that takes care of my lashes! If you curl them along your eye line, it creates a natural and beautiful curl!! Please be careful not to press too close, as you might pinch your eye, so just use it gently(?) haha. If you want a tighter curl, you can do it several times, and make sure to apply mascara afterward to maintain the curl~~ It has a great grip, so it is really comfortable to use haha. As a side note, I recommend buying the rubber tips so you can use it for a long time!!
